Biosample
Description
From prometaphase to anaphase oocyte from 7 to 9 week-old-mouse, in which chromosomes and kinetochores were visualized. For Rec8 TRIM-Away experiment control-IgG was injected.
Extrinsic Variable
To visualize chromosomes and kinetochores, in vitro
transcribed mRNAs for H2B-SNAP and
tdTomato-CENPC (centromere
protein C) were injected. For TRIM-Away method, 0.38 pg TRIM21 and 0.19 to 0.23 pg rabbit control IgG were injected.
